When trying an emerge -uD xine-lib I get a compile-time error. The problem is somewhere in the assembler code. X86 assembler is just not my bag... Another thing: The only included header files in zoom_filter_xmmx.c is goom_config.h and xineutils.h, none of them mentions the missing prototypes: zoom_filter_xmmx_supported and zoom_filter_xmmx. That's just ugly. AND the comments! They are in french! uh! I suppose this is something we got from upstream? Or do gentoo-devs do such things? Reproducible: Always Steps to Reproduce: 1. Just try to emerge the xine-lib-1_rc1 ebuild 2. 3.

please provide #emerge info

play with your CFLAGS ... try it with march=pentium3 instead of pentium4 ... if that doesnt work, try it with just -pipe
Same at my my side, decreasing CFLAGS (which worked for other xine-lib before) will help!
Setting CFLAGS="-march=pentium3 -O3 -pipe -fomit-frame-pointer" did the trick. So there are still glitches in the gcc regarding pentium4 code generation... or?
I also had the issue. I can confirm that changing the CFLAGS from march=pentium4 to march=pentium3 will fix it.
This isn't explicitely caused by -march=pentium4, but is caused by the fact that -march=pentium4 implies -msse2 - this can be demonstrated by changing your CFLAGS to '-march=pentium3 -msse2 ...'. A better fix is to leave the -march=pentium4 in there, and add "-mno-sse2" to your CFLAGS - this will also fix the problem, without sacrificing other gcc pentium4 compiling tweaks.
so the solution here is: inherit gcc flag-o-matic [ "`gcc-fullversion`" == "3.3.1" ] && [ `is-flag -msse2` -o `is-flag -march=pentium4` ] && append-flags -mno-sse2
fixed in cvs
